The focus of Pl el-Hedim is the huge gate of Bab el-Mansour, the grandest of all imperial Moroccan gateways. The gate is well preserved with lavish (if faded) zellij and inscriptions across the top. It was completed by Moulay Ismail’s son, Moulay Abdallah, in 1732. You can’t walk through the bab itself (although it’s sometimes open to host exhibitions), but instead have to make do with a side gate to the left.
